No launcher icon after install apk

Question

I've build apk and after install no icon in launcher. App works correctly and i can start activity with adb. But why app no icon in launcher i can't understand.

<?xml version="1.0" encoding="utf-8"?>  
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    .....skiped....
    <application
        android:name="DialerApplication"
        android:label="@string/applicationLabel"
        android:icon="@mipmap/ic_launcher_phone"
        android:hardwareAccelerated="true"
        android:supportsRtl="true"
        android:backupAgent='com.android.dialer.DialerBackupAgent'>

        <meta-data android:name="com.google.android.backup.api_key"
            android:value="AEdPqrEAAAAIBXgtCEKQ6W0PXVnW-ZVia2KmlV2AxsTw3GjAeQ" />


        <!-- The entrance point for Phone UI.
             stateAlwaysHidden is set to suppress keyboard show up on
             dialpad screen. -->
        <activity android:name=".DialtactsActivity"
            android:label="@string/launcherActivityLabel"
            android:theme="@style/DialtactsActivityTheme"
            android:launchMode="singleTask"
            android:clearTaskOnLaunch="true"
            android:icon="@mipmap/ic_launcher_phone"
            android:enabled="@*android:bool/config_voice_capable"
            android:windowSoftInputMode="stateAlwaysHidden|adjustNothing">
            ......skiped......
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.LAUNCHER" />
                <category android:name="android.intent.category.BROWSABLE" />
            </intent-filter>
            ......skiped......
        </activity>

    ......skiped..........
    </application>
</manifest>

It seems like i see cause of problem. If i try start my app with adb "adb shell am start mypackagename" i get error:

Activity not started, unable to resolve Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER]

But i set in AndroidManifest intent-filter for action android.intent.action.MAIN and category android.intent.category.LAUNCHER.

Why android don't register action and category for main activity?

Link to full AndroidManifest: https://github.com/Anton111111/android_packages_apps_Dialer/blob/cm-12.1_dialer_for_xperia/AndroidManifest.xml

It seems like android full ignores all my intent-filters for activity .DialtactsActivity.

and in the mipmap folders you definetly have ic_launcher_phone png icon ?? -- if so you may need to rename it to ic_launcher - probably not accepting anything but ic_launcher -- try that -- and you dont need (android:icon="@mipmap/ic_launcher_phone") in the activity -- just in Application is fine — Tasos, Sep 20 '15 at 07:47
another hint is that if you are using an emulator there's quite a few icons so there is a 2nd page you can slide with the mouse, You App icon may be on the 2nd page — Tasos, Sep 20 '15 at 07:57
What device? Is is default launcher? What Android version? Some android versions may not like @mipmap. Try putting the icon into the drawable folder and do @drawable/... — Gunnar Karlsson, Sep 20 '15 at 08:46
I think that problem not in icon because i have another app with android:icon="@mipmap/ic_contacts_clr_48cv_44dp" and it works correctly and has icon in launcher. And if i go to settings-applications and find my app i see that app has icon. — Anton111111, Sep 20 '15 at 09:12

Define multiple intent filters for their specific purposes:

<activity>
    <intent-filter>
        <!-- This will put the activity in launcher. -->
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>

    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <!-- Include the host attribute if you want your app to respond
             only to URLs with your app's domain. -->
        <data android:scheme="http" android:host="www.example.com" />
        <category android:name="android.intent.category.DEFAULT" />
        <!-- The BROWSABLE category is required to get links from web pages. -->
        <category android:name="android.intent.category.BROWSABLE" />
    </intent-filter>
</activity>

I've already troed make multiple intent filters. It's not solve my problem ;( – Anton111111 Sep 20 '15 at 14:57
Assuming the icon and label are non null the only suspicious value is this `@*android:bool/config_voice_capable`. If you set it to `true` is the icon still missing from launcher? – Eugen Pechanec Sep 20 '15 at 14:59
You are right. I taked out andoid:enabled from manifest and now i see icon. – Anton111111 Sep 20 '15 at 15:20

    <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.DEFAULT"/>
            <category android:name="android.intent.category.LAUNCHER"/>
    </intent-filter>

Make it As

    <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
    </intent-filter>
